| 摘 要： | 在准噶尔盆地,以断裂为主,联合输导层(储层和不整合)的“断控体系”是油气运移的基本固体格架。文中从油气形成和演化过程中的有机-无机相互作用入手,分析了准噶尔盆地油气运移的基本方式和机理。结果表明,油气在输导层运移过程中,随有机质热演化、成岩演化,以及距油源断裂的远近不同,伴随着的水量有着显著变化。流体性质的差异导致了不同的储层水岩反应和油气成藏机制,据此,可将油气在输导层中的运移方式划分出两种基本类型:机械-侵蚀型和机械型。而在断裂带地区,断裂对储层中高压流体系统的沟通,触发了“减压沸腾”作用,伴随着流体沸腾,油气呈幕式运移聚集。 |

| Abstract: | In the Junggar Basin, petroleum generally migrates along reservoir rocks (including unconformity) and faults. In this paper, the basic styles and mechanism of petroleum migration were analyzed, based on organic-inorganic interaction during hydrocarbon formation and evolution. It is shown that in reservoir rocks, based on the characteristics of petro-fluid, oil-gas migration styles vary in mechanical-solution and mechanical characteristics, respectively. The factors controlling this fluid heterogeneity include organic matter maturation, diagenetic evolution and the distance from thrust faults. In contrast, in fault zones, petroleum migration is characterized by the accumulation of reservoir formation pressure, and a later hydrocarbon boiling under release of high formation pressures caused by faults. Along with this fault pumping, hydrocarbons and fluid migrate and accumulate episodically. |
